Description

Technical Field

[0001] The invention relates to the technical field of vehicle stoppers, in particular to a trackless rubber-wheel parking stopper. Background Art

[0002] Most coal mines adopt the inclined shaft development method, and the roadway pavement is paved with concrete. When the mine trackless rubber-tyred vehicle goes down the long slope roadway, the vehicle may lose control, the brakes may fail, and other emergencies may occur, which can easily cause major safety accidents. According to the relevant national regulations on the transportation of mine trackless rubber-tyred vehicles and Article 392 of the "Coal Mine Safety Regulations", vehicle stall safety measures must be taken in the long slope roadway. The traditional car blocker is manually set by the driver and passengers when the driver and the vehicle are separated. The intelligent pneumatic car blocker allows the driver and passengers to start it with one button without leaving the cab, and the car blocker is automatically set at the specified position, which greatly improves the safety management level of underground transportation.
